In other words, the answer to the original question is, "the Sequent works just like your NCR system." The big difference is the Sequent (and Arete, Encore, Elxsi, and Pyramid) run symmetric multiprocessors, while NCR (and CCI, DEC, and a bunch of others) run master/slave. The above machines are all general purpose multi-user UNIX boxes that simply use multiple CPUs as a cost effective way to boost multi-tasking performance. Generally, if your objective is to do "real" parallel processing, buy a ma- chine designed for the job: Multiflow, BB&N Butterfly, et al. <csg>
